As of September 2016, the International Union for Conservation of Nature (IUCN) lists 643 endangered fish species. 4.2% of all evaluated fish species are listed as endangered. The IUCN also lists ten fish subspecies as endangered.

Of the subpopulations of fishes evaluated by the IUCN, 24 species subpopulations have been assessed as endangered.

For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered fishes are listed separately. There are 1098 fish species which are endangered or critically endangered.

Additionally 3191 fish species (21% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed.

List of few endangered fish species include the following:

• Achondrostoma occidentale
• Achondrostoma salmantinum
• Bakır Shemaya (Alburnus attalus)
• Antalya bleak (Alburnus baliki)
• Manyas shemaya (Alburnus carinatus)
• Green labeo (Labeo fisheri)
• Tana labeo (Labeo mesops)
• Labeo potail
• Labeobarbus ethiopicus
• Labeobarbus macrophtalmus, etc.

In this Research Topic collection we invite researchers to submit manuscripts along the following themes:

Manuscript contributions that deal with Conservation of fish, Preservation of DNA of endangered fish, Methods of conservation of fish, etc.

-               Interdisciplinary research, observational field studies, experiments or manipulations, meta-analyses, reviews or modeling approaches are also welcome.

Journal of Fisheries Research is now accepting submissions on this topic. A standard EDITORIAL TRACKING SYSTEM is utilized for manuscript submission, review, editorial processing and tracking which can be securely accessed by the authors, reviewers and editors for monitoring and tracking the article processing. Manuscripts can be uploaded online at Editorial Tracking System (https://www.scholarscentral.org/submissions/fisheries-research.html) or forwarded to the Editorial Office at fisheriesres@emedscholar.com
